That is awesome that you kept it off for 13 years! My mentality is definitey different than it was 6 years ago too.
I'm sure you're right and my metabolism isn't great anymore. The times that seem to be the hardest for me is in the evenings and weekends. Times that I am with my husband mostly. It's not that he's not supportive, he really is. We've just gotten into these habits of eating and drinking certain things and that is hard to break. Then I come from a huge family that all live close together. On weekends there seems to always be something going on. Again, if I were to say that I couldn't have something because I'm on WW's everyone would understand and try to have other options. So it really should be easier to do than this.
